IMPROVEMENT IN WATER-CLOSET VALVES.

The Schedule referred to in these Letters Patent and making part of thesame.

1, WILLIAM GORDON, of the city of Philadelphia and State ofPennsylvania, have invented certain Improvements in Water-Closet Valves,of which the following is a specification,

The nature of my invention is as follows:

The valve is provided with a vacuum-chamber, into which water passesthrough a channel which leads from the water-chamber, the said channelbeing opened and closed by means of an adjustable screw to regulate themovements of the valve, and consequently the flow ofwater through thedischarge-pipe, as hereinafter described.

The valve-chamber is combined with a stationary bucket, that has acounter-pressure of water exerted by the water in the water-chamber,whereby a tight and easy fit is secured.

To enable others skilled in the art to which my improvement appertainsto make and use my improved valve, 1 will now proceed to give a fulldescription thereof.

In the accompanying drawing which makes a part of A this-specification-Figure 1 is a side elevation of the improved valve.

Figure 2 is a vertical section at the line :v x offig. 1.

Figure 3 is a plan view of the plate E, provided with the centralbucket-support f.

Figure 4 is a side elevation of the same.

Figure 5 is .a side elevation of the valve B.

Like letters in all the figures indicate the same parts.

A is the valve-case, which has an induction-opening, a, and anexit-opening, b.

B is the valve, whose stem, (1, works in the stuflingbox 0.

The valve is provided with a leather or other elastic ring, -D, aroundits stem d, whereby a tight and easy fit is made with the seat e.

The central stem f of the crown-plate Eof the case A has a centralopening, g, in which is placed the wire spring F, that bears the valveagainst its seat to close the same, and yields to the force of thelever, allowing the water to escape through exitopening b.

The central stem 1' of the crown-plate E is provided with a leather orother elastic bucket, G, seen in fig. 2.

The upward pressure of the water in the chamber 7b of the case A, and onthe under side of the bucket G, closes the latter against the side ofthe vacuumchamber j, thereby giving an elastic fit to said bucket,allowinga free up-and-down movement of the valve.

The central screw H is connected with the crownplate E for regulatingthe flow of water from the chamber h, through the passage 7:, into thevacuumchamber j, thereby causing a quick or slow movement of the valve Bto regulate the flow of water through the exit-opening I1.

The upper end of said screw H is provided with a valve, Z, and thechamber m of the plate E with a valve-seat, n.

\Vhat I claim as my invention, and desire to sesure by Letters Patent,is-

1. The central openingg of the stem f, in combination with the spring Iand valve 13, substantially as and for the purpose set forth.

2. The combination and arrangement of the passage with the centralopening 9 and water-chamber 71., as and for the purpose described.

3. The combination of the adjustable valve-screw H with the crown-plateE, arranged and operating in relation to the passage It andvacuum-chamber j, substantially as and for the purpose set forth.

In testimony that the above is my invention I have hereunto set my handand afiixed my seal this 28th day of November, 1870.
